Oil Drain Intervals on the Rise
The 3,000 mile oil change interval
has been ingrained in the American consciousness for decades.
Conventional motor oil companies aggressively push it, oil
change centers remind their customers to return when another
3,000 miles have accumulated on the odometer and fathers teach
their children to change their oil and filter according to
a 3,000 mile schedule.
on the other hand, aren't quite on the same page. A look at
many recent-modern owners manuals reveals a recommended 5,000-
to 7,500-mile oil drain interval, while European vehicle manufacturers
recommend even longer drain intervals. As the service lives
of spark plugs and transmission fluids have increased, consumers
have demanded longer service intervals for motor oil as well.
The introduction of electronic oil life monitors on modern
vehicles is beginning to push drain intervals upward. Oil
life monitors typically determine when oil should be changed
based on engine operating conditions such as temperature,
revolutions and speed.
Almost all 2005
and later General Motors vehicles are equipped with its Oil
Life System, which makes use of a color-coded system to alert
the driver when it's time to change the oil. A "yellow"
condition indicates that it's time to think about changing
the oil, while a "red" condition indicates that
the oil is past its service life. According to GM, the typical
drain interval for vehicles equipped with the Oil Life System
is 8,500 miles, which will result in a savings of 6.6 million
gallons of oil and $145 million for 2005 model-year drivers
over the lives of their vehicles.
is actively seeking to extend oil drain intervals even further.
In fact, the company recently asserted that 20,000-mile oil
drain intervals are possible with existing engine technology
and synthetic oils meeting current specifications, while 30,000-mile
oil change intervals are achievable with appropriate motor
oil quality and minor engine modifications.
are a very specific goal for GM, and are being managed in
a logical and planned fashion," says James A Spearot,
director of GM's Chemical & Environmental Sciences Laboratory
in Warren, Michigan. "Longer drain intervals are desirable
to meet customer demands for reduced maintenance and convenience,
and for the environmental benefits that come with less oil
handling. And, in the end, longer drain intervals will help
us with our warranty protection goals."
the lone voice for extended drain intervals in America for
over 30 years, recommending 25,000-mile/one-year drain intervals.
While extended oil drain intervals have been common in Europe
for years, other American motor oil companies have mostly
avoided recommending them, preferring instead to stick with
3,000-mile recommended intervals despite the contrasting recommendations
of vehicle manufacturers and European motor oil companies.
In fact, Marc Graham,
president of Pennzoil-Quaker State-owned Jiffy Lube International,
was quoted in a 2001 Lubricants World interview as
saying, "At [Pennzoil-Quaker State] we use a number internally
that if we [shorten the drain interval] by 100 miles [for
each car serviced], it would mean an additional $20 million
in revenue for the company." He also explained that "if
we could move our customers to get one more oil change per
year, it's worth $294 million for the oil change alone and
$441 million in revenue, when you include the ancillary products
and services customers typically buy along with the oil change."
Today, with vehicle
manufacturers recommending longer and longer drain intervals
and the increasing use of oil monitoring systems, the practice
of extending drain intervals has become more mainstream and
forced more motor oil companies to take notice. ExxonMobil,
for example, recently introduced a line of long drain motor
oils, and other motor oil companies will likely follow.
As more motor oil companies begin offering extended drain
motor oils, the extended drain interval idea pioneered by
AMSOIL over 30 years ago will become increasingly common.
According to a
special report released May 2005 by the Motor & Equipment
Manufacturers Association (MEMA), synthetic motor oils are
key to extended drain technology: "Extended drain technology
is primarily based on the availability of synthetic oils.
While the additives in conventional, non-synthetic oils allow
them to function longer than the traditional 3,000 miles,
it is primarily the synthetic base stocks that allow the oil
to last much longer. Synthetic oil offers many advantages
in durability versus conventional petroleum oil and it is
all based on the synthetic oil's superior heat and oxidation
resistance. Synthetic oil is more accurately controlled at
the molecular level and therefore can be engineered to resist
the forces in an engine that work against oil durability."
AMSOIL offers a
complete line of premium quality synthetic motor oils formulated
for extended drain intervals.

Why Motor Oil Deteriorates
It is common knowledge
that, at some point, engine oil must be changed. It's something
that is preached relentlessly to vehicle owners by vehicle
manufacturers, quick lubes and oil companies. But consumers
are widely unaware of what exactly makes oil changes necessary.
Many factors contribute
to a motor oil's demise, but it is essentially the accumulation
of contaminants in the oil and chemical changes in the oil
itself that make a motor unfit for further service. With time,
it is inevitable that the oil will be contaminated by dirt
or sludge, or succumb to the extreme pressures or temperatures
found inside an engine. AMSOIL Motor Oils are formulated with
the industry's most advanced synthetic base stocks and additive
packages to combat the forces that deteriorate conventional
What is the NOACK Volatility
Volatization is a term used to describe
what happens to a fluid as it is heated to the point it begins
to "boil off." Upon reaching a certain temperature,
oil will begin to lose some of its lighter weight molecules
as they "boil off" and leave heavier weight molecules
behind. Not only does this cause higher oil consumption, this
process can also cause increased viscosity making the oil
more difficult to circulate through the lubrication system.

synthetic motor oils are formulated to surpass engine test
specifications, offering protection far greater than competing
motor oils for extended drain intervals. Most synthetic oil
manufacturers make no claim to extended drain intervals, deferring
to the maintenance schedule provided by the vehicle manufacturer.
With its unparalleled oil and warranty program, AMSOIL offers
consumers unprecedented protection and economics.
More than 20 years
ago, AMSOIL began using the NOACK volatility test as a comparison
tool and measurement of quality. Back then, nearly every oil
tested side-by-side with AMSOIL synthetic motor oils failed,
and those that passed barely squeaked by. Other oil companies
paid no attention to NOACK results until Ford Motor Company
made it a requirement for service fill oils, validating what
AMSOIL had said all along.
NOACK Volatility Test
Volatility Test determines the evaporation loss
of lubricants in high temperature service. The more
motor oils vaporize, the thicker and heavier they become,
contributing to poor circulation, reduced fuel economy
and increased oil consumption, wear and emissions. AMSOIL
Synthetic Motor Oil resists high temperature volatization
better than other motor oils. AMSOIL Synthetic Motor
Oil maintains peak fuel efficiency and reduces oil consumption
